Bismuth oxychloride hollow microspheres with high visible light photocatalytic activity

, 2016
Hollow microspheres of two bismuth oxychlorides, BiOCl and BiOCl, were successfully synthesized using carbonaceous microsphere sacrificial templates. The phase evolution from BiOCl to BiOCl was easily realized by heating the former at 600 °C.

Preparation of Polymeric Hollow Microspheres.

KAGAKU KOGAKU RONBUNSHU, 1997
Polymeric hollow microspheres of a few ten μm in diameter were prepared by removal of the encapsulated solution from polymeric microcapsules by in situ polymerization. As a result, no rupture of microcapsules occured and a high yield of polymeric hollow microspheres was obtained under the condition of lower ratio of the encapsulated solution to monomer
